Chip-on-Board LEDs Target 40-W and 60-W A-Bulb Replacement

LISTED UNDER:

Everlight announced its Chip-on-Board (COB) LED series for general lighting replacement applications. To replace 40W and 60W incandescent A-bulbs, the company created an LED to address heat dissipation, color shift over time and temperature, light distribution and cost. Everlight’s COB LED series is a MCPCB-substrate based multi-chip solution that touts a >95 lm/W at 3000K CCT and >80 CRI. Less layers of thermal resistance result in lower overall junction temperature. A new patent pending Everlight technology is able to address the Hot/Cold Factor, the color uniformity as related to change in temperature. From 25°C to 85°C, the COB LED can control CCT shift to within 200K CCT for all wattages. A large single light emitting source means less diffusion needed to achieve high uniformity and light distribution.
